Resumo
Several technologies for the development of new sugarcane cultivars have mainly focused
on the increase in productivity and greater disease resistance. Sugarcane cultivars are usually
identified by the organography of the leaves and stems, the analysis of peroxidase and esterase
isoenzyme activities and the total soluble protein as well as soluble solid content. Nuclear magnetic
resonance (NMR) associated with chemometric analysis has proven to be a valuable tool for
cultivar assessment. Thus, this article describes the potential of chemometric analysis applied to
1H high resolution magic angle spinning (HRMAS) and NMR in solution for the investigation
of sugarcane cultivars. For this purpose, leaves from eight different cultivars of sugarcane were
investigated by 1H NMR spectroscopy in combination with chemometric analysis. The approach
shows to be a useful tool for the distinction and classification of different sugarcane cultivars as
well as to access the differences on its chemical composition.
